The Devil You Know

It was the crime that captivated Australia and made headlines day after day.

On May 20, 2014, 20-year-old university student Jamie Gao was shot dead inside a Padstow storage shed in Sydney's south west. Six days later his body would be found by fishermen, stuffed inside a surfboard bag floating off the Cronulla coastline.

Damning security footage put two men inside that shed with Gao – former NSW detectives Roger Rogerson and Glen McNamara.

Both pleaded not guilty to the shooting murder and a separate charge of taking part in the supply of 2.7kg of ice.

During the four-month trial Rogerson and McNamara pointed the finger at each other for the murder. Today, a jury found both men guilty on all charges.
